30 gen 25000 anni a. C. - Cosquer Cave, a paleolithic cave art site in France,
is situated 120 feet below sea level.
The paintings are from 27,000 years ago,
and the cave would have been accessible during that time due to the decreased sea levels.
The paintings show a number of extinct animals,
like the megaloceros deer,
a very large variety,
as well as ibex, seals and great auks.
